Freak (l'auteur de l'IDE) explique sa méthode pour gérer un programme plurilingue.
Je recopie le code ici pour éviter les problèmes de liens
le fichier german.prefs pourrait ressembler à ça:

; Example of a simple language management for programs
; -----------------------------------------------------------------
;
; Benefits of this solution:
; - Strings are identified by a Group and Name string, which allows to
; organize them with descriptive names and makes coding easier.
;
; - Strings are sorted and indexed when they are loaded, which gives
; a fast access even though they are accessed by name.
;
; - A default language is defined in the code (DataSection), so even if
; external language files are missing or outdated, there is always a
; fallback string present.
;
; - The list of strings is easy to extend. Simply add a new entry in the
; DataSection and the language files and use the new Group and Name.
;
; - Additional language files are in the PB Preference format which makes
; them easy to maintain.
;
; Usage:
; - define the default language in the DataSection like shown below
; - Use LoadLanguage() at least once to load the default language or external file
; - Use Language(Group$, Name$) to access the language strings
;

; This procedure loads the language from a file, or the default language.
; It must be called at least once before using any language strings.
;
; It does this:
; - load & sort the included default language
; - load any additional language from file
;
; This way you always get a language string, even if the file is not found
; or a string entry is missing in the file. You will still get the default
; language when using tha Language() command.
;
; This function can be called multiple times to change the used language
; during runtime.

, si non je serai passer par procédure mais c'était juste pour montrée comment faire facilement un multi langues.
